⚾ Starting Pitchers
Carson Palmquist will take the mound for Washington with a record of 0-1, an ERA of 8.74, and 14 strikeouts. The left-hander has yet to prove his ability to consistently navigate through the early innings at the MLB level. Arizona boasts several right-handed hitters capable of quickly capitalizing on his loss of control and pitches left over the heart of the plate.
Eduardo Rodriguez will start for the visitors with a record of 8-3, an ERA of 2.62, and 82 strikeouts. The left-hander is having one of the most consistent seasons in Arizona's rotation and rarely allows opponents to string together multiple scoring opportunities. His control provides the visitors with the chance to take their time on offense and gradually build their lead.
⭐ Editorial Prediction
Washington are in solid offensive form, having won six of their last 10 head-to-head encounters, so the visitors shouldn't expect an easy game. However, the disparity between the starting pitchers is quite evident: Rodriguez boasts an ERA of 2.62, while Palmquist's stands at 8.74. Arizona just put up ten runs, showcasing their depth even without one of their key players. If the visitors can establish an early lead, Rodriguez and the late relievers are capable of maintaining that advantage. The standings also demand that the Diamondbacks play with maximum focus against a direct competitor. In this matchup, we are backing an Arizona Diamondbacks win.
